There's this medieval lute joke (he says, diverting the talk away from banjos):

"If a man hath a lute for 60 years, he shall spend 40 of them tuning it and 20 playing it out of tune."

This actually IS a medieval joke.

Skeleton goes into a bar and says, "Pint of beer and a mop please".

There was this Englishman, this Irishman and a banjo player...
